Slight gas smell from boiler at ignition and shutdown

We just bought this house and I noticed that if you have your head down by the igniter/jets of the boiler you can briefly smell gas when it kicks on and for a few minutes after it has shut down, but never while it's burning. It's an older dunkirk model boiler.
Within maybe 5-10 minutes of being shutdown the smell goes away completely and doesn't come back until the next ignition, goes way while burning and briefly comes again after shutdown.
I have a handheld gas leak detector and it's enough to make it go off if held down there during ignition, and for a few brief seconds after shutdown.
Any thoughts would be appreciated, as i've never owned a gas boiler before and it's kind of freaking me out!

And so it should -- freak you out, that is. It would be a very good idea to have a tech. knowledgeable in gas burners check it, as it really shouldn't do that.Br. Jamie, osb

On a lot of older systems as they age you will get a slight odor when they come on and shut off if you get right down near the burners. If you are concerned and want it checked then call in a smell of gas to the local gas company and have them check it. I have over 50 years in the gas industry so you can trust my answer.0
